Problem 9 shows a circle with a tangent line. An angle of 110 degrees is indicated, likely an arc. The variable 'x' represents an angle formed by the tangent and a chord. To solve for 'x', one would typically use the theorem that states the angle formed by a tangent and a chord is half the measure of the intercepted arc. Thus, if 110 degrees represents the intercepted arc, then x would be 110 / 2 = 55 degrees.
